Linux syslog 系统日志管理
===============================================================================
rsyslog记录日志于mysql：
操作如下：
实验环境：CentOS 7 操作系统
前提：
准备好msql server或mariadb server（一定要编辑配置文件/etc/my.cnf,添加跳过反向解析等）并启动服务；
实验步骤：
1.安装rsyslog连接至mysql server的驱动模块；
# yum install rsyslog-mysql
2.在mysql server准备rsyslog专用的用户账号；
[root@centos7 ~]# mysql -p
Enter password:

Bye3.生成所需要的数据库和表；
前面已经安装了rsyslog连接至mysql server的驱动模块rsyslog-mysql，查看其配置文件如下：
[root@centos7 ~]# rpm -ql rsyslog-mysql
/usr/lib64/rsyslog/ommysql.so
/usr/share/doc/rsyslog-7.4.7/mysql-createDB.sql # 是生成数据库和表的一个脚本文件
[root@centos7 ~]# cat /usr/share/doc/rsyslog-7.4.7/mysql-createDB.sql
CREATE DATABASE Syslog;
USE Syslog;
CREATE TABLE SystemEvents
(
ID int unsigned not null auto_increment primary key,
CustomerID bigint,
ReceivedAt datetime NULL,
DeviceReportedTime datetime NULL,
Facility smallint NULL,
Priority smallint NULL,
FromHost varchar(60) NULL,
Message text,
NTSeverity int NULL,
Importance int NULL,
EventSource varchar(60),
EventUser varchar(60) NULL,
EventCategory int NULL,
EventID int NULL,
EventBinaryData text NULL,
MaxAvailable int NULL,
CurrUsage int NULL,
MinUsage int NULL,
MaxUsage int NULL,
InfoUnitID int NULL ,
SysLogTag varchar(60),
EventLogType varchar(60),
GenericFileName VarChar(60),
SystemID int NULL
);
CREATE TABLE SystemEventsProperties
(
ID int unsigned not null auto_increment primary key,
SystemEventID int NULL ,
ParamName varchar(255) NULL ,
ParamValue text NULL
);直接把脚本导入数据库中
[root@centos7 ~]# mysql -ursyslog -h227.0.0.1 -p134296 < /usr/share/doc/rsyslog-7.4.7/mysql-createDB.sql
# 登录数据库查看如下：
[root@centos7 ~]# mysql -ursyslog -h227.0.0.1 -p134296

Aborted4.配置rsyslog使用ommysql模块
[root@centos7 ~]# vim /etc/rsyslog.conf
#### MODULES ####
......
$ModLoad ommysql
5.配置RULES，将所期望的日志信息记录于mysql中；
facility.priority :ommysql:DBHOST,DB,DBUSER,DBUSERPASS
6.重启rsyslog服务；登录数据库查看如下
# systemctl start rsyslog # 重启服务
[root@centos7 ~]# mysql -ursyslog -h227.0.0.1 -p134296

# 到原来的目录中找到contrib目录，这里面有两个脚本，可以帮助我们配置源码。
[root@centos7 loganalyzer-3.6.5]# ls contrib/
configure.sh secure.sh
[root@centos7 loganalyzer-3.6.5]# cp contrib/* /var/www/html/log/ # 复制过去
[root@centos7 log]# cat configure.sh # 从安装步骤中得知要先执行此脚本
#!/bin/sh
touch config.php
chmod 666 config.php
[root@centos7 log]# cat secure.sh
#!/bin/sh
chmod 644 config.php # 安装完成之后执行此脚本
[root@centos7 log]# touch config.php # 因为太简单所以，自己手动修改即可
[root@centos7 log]# chmod 666 config.php2）准备amp环境，这里以httpd+php为模块的方式
3）安装配置如下图
注意：这里localhost应该改为127.0.0.1 编辑配置文件config.php即可
安装php-gd可以显示柱状图
步骤总结如下：
